The lights on the front cap of my camper are red. They are just there to highlight the front while your camping. I'm not sure why they picked red for the front. If someone forgets to turn them off before towing, it could cause issues with traffic. I've seen blue in the same place on other campers, just to highlight it and also to keep you from whacking your head while walking around at night.
